I recently updated my computer to Gnome-3.8 and systemd. In the process, I simplified my USE-flags considerably. After the update, it seems that most things work fine. There is one minor nuisance, which is that some streaming content in flash is no longer played back correctly. Most of YouTube plays fine, but for instance a hotel website where I wanted to book a room was not visible - just white, black and red patches. I have used that site before without problems.

I have set the ffmpeg flag, and tried with several other USE flags but until now no effect. Does anybody recognize this problem?

I have seen this before, I think. Since flash is a closed source package, I don't think emerging stuff will fix much...

I however think it has something to do with the video driver - what video card are you using? The machine I have that exhibits this issue is an 3g Core i5 built-in graphics... And it exhibits this behavior when the flash window is partially obscured by scroll bars. But it's the only machine I've seen this on...

I'm going to bump this. I recently had another issue with my flash...well, it... flashes.

Meaning that some flash windows within firefox seems to be flashing at about 5Hz. I think this is cross-hardware now as my ati fglrx box also is also exhibiting the problem..._________________Intel Core i7 2700K@ 4.1GHz/HD3000 graphics/8GB DDR3/180GB SSDWhat am I supposed to be advocating?

Mhm... I have problems with flash, too. Can't tell when exactly it started, must have been 2 or 3 weeks ago.

In principle, flash works fine with Firefox here. But it fails as soon as the flash-content reaches the edge of the window. This means that I can play YouTube (even fullscreen) as long as I keep the window as it is, but as soon as I scroll down and make the video touch the upper edge, it's like Lego stones allover. Like MPEG-artifacts, only more chaotic and bigger.

It's especially annoying with big Flash-based ads that usually sit on the side of the viewable area. The whole thing flickers so much it could probably cause seizures.

Funny thing is that Opera, on the very same web pages, shows no such problems.

I picked up flash 11.2.202.297 on Jul 31ish 2013. I'm not sure when I started seeing this problem, it may be partially to do with firefox 17.0.8 as well, which I emerged on Aug 14 2013...

I'll have to see what the behavior of my other machines that I have not updated and ones that have problems, might be an upstream problem with one or the other..._________________Intel Core i7 2700K@ 4.1GHz/HD3000 graphics/8GB DDR3/180GB SSDWhat am I supposed to be advocating?

I have found the source of the problem, but don't know how to fix it. The problem seems to be connected, in my case, with adblock plus being on. If I disable adblock, everything works fine again. Of course, that's not an ideal situation, but it suggests where the problem lies.

Thanks, but that's not the problem I'm trying to address. The problem, as noted in the thread, is distortion and the inability to watch some videos. Having adblock plus installed seems to lead to this problem or at least contribute to it.

I get completely garbled video on certain sites using certain players. Youtube and dailymotion are fine, content on some other sites like skysports.com are perfect in full screen but completely unwatchable in an embedded frame. I don't use an extension to block ads, I do that with /etc/hosts.

It's kind of funny: The garbled flash that I see are mostly advertisements. Perhaps it's the advertisers' best interest to fix this else we're not seeing their ads :)_________________Intel Core i7 2700K@ 4.1GHz/HD3000 graphics/8GB DDR3/180GB SSDWhat am I supposed to be advocating?

I also just tried to remove the .mozilla directory to try and isolate a bad setting. That didn't help either.

Final update. It's definitely flashplayer.so. I downloaded an older version (ffp_10.3.183.90_archive.zip) rom the Adobe archives, copied libflashplayer.so into the directories its usually found in and video works flawlessly.

Yes, 297 does not work. I was just updating my netbook that had 297 installed with firefox 10.0.6 which had the drawing issues. So it's definitely a flashplayer problem...

And *sigh* all old portage versions are gone... Would need to grab an old one from Adobe if they still have..._________________Intel Core i7 2700K@ 4.1GHz/HD3000 graphics/8GB DDR3/180GB SSDWhat am I supposed to be advocating?

Oddly enough, I am running version 11.2.202.310 on my work computer (Ubuntu) and cannot detect the problem. That machine is not running off a nvidia card, but only what comes built into an i5 processor.
